DISPENSING DEVICE.

Patented July 16, 1918.

Application filed January 13, 1915, Serial No. 1,922. Renewed March 16, 1918. Serial No. 222,983.

To all whom it may concern: I

Be it known that I, BERTHOLD JAHN, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Dispensing Devices, of which the following is a specification.

This invention relates to dispensing devices and particularly to devices of the class specified adapted fordispensing stacked or nested articles. I

The object of my improvements is to provide a dispensing device simple in construction, reliable in operation and economical to manufacture.

l/Vith these ends in viewmy improved-device comprises features illustrated in theaccompanying drawings and which drawings show the device as particularly adapted for dispensing flanged pa percups froma nested stack. Said drawings show the preferred embodiment of my improvements as directed to this result. Therein Figure 1 is a plan view of my improved device with that portion ofc the casing above line 11 of Fig. 2 removed and with the cups omitted.

Fig. 2 is a sectional elevation corresponding with Fig. 1. the section being taken 'on line 22 of said Fig. 1. Fig. 3 is a plan view of a portion of what is shown in Fig. 1 and illustrating the mid-position of one of the escapements. is shown in Fig. 3 and looking. in thedirection of arrow A of said Fig. 3. Fig. 5 is a plan view similar to that of F igl 3 but showing the escapement at the completion of its stroke. Fig. 6 is an elevation of what is shown in Fig. 5 and looking in the direction of arrow B of said Fig. 5. Fig. 7 is another elevation of what-is shown in Fig. 5 and looking inthe direction of arrowG of said Fig. 5. Fig. 8 is a plan view 'of a portion of what is shown in Fig. 1 but with the escapement removed. All the figures of I the drawing are to the same scale.

Theessential feature ofmy improvements comprises an 'oscillatable escapement, indicated in a general way by 2, Fig. 1, having three blades, 3, 4 and 5. Blades 3 and 5 are fixed relatively to each other, in parallel planes and remote from each other.

Fig. 4 is an elevation of what j Blade 4 in its inoperative position lies closely contiguous and parallel to blade 3,

and in its operation moves away from said blage 3, toward or beyond the plane of bla e 5.

The material of blade 3 is extended around in U shaped formation, thus forming a vertical wall 6 and alower horizontal member 7. Blade 5, by a downwardly and out- -wardly reaching extension thereof, is rigidly connected to said horizontal member 7. Movable blade 4, by'means of a vertical extension thereof, is pivotally supported at 8 to said vertical wall 6 of blade 3. A further rearwardly extending portion of blade 4 carries a cam engaging foot 9. Es-

capement unit 2 as a whole, is oscillatably being provided with a downwardly-reaching pin 14' projecging through radial slot 15 in said plate 1 so that when plate 13 is oscillated, escapement 2 will also be caused to oscillate. Said plate 13 has cam portions as 16 upstanding thereon for engagement with feet as 9 of the rearwardly eX- tending portions of blades 4. Thus when escapement 2 is oscillated by the movement of plate 13, blade 4 will be caused to move away from blade 3, said blade 4 being returned to its normal position contiguous to blade 3 by the action of tension spring 17 Movable plate 13 is shown slightlyseparated from fixed plate 11 by means of washers about posts 10, said plate 13 being provided with concentric slots as 18 to allow for movement about said posts. Plate 13 is also provided with handle 19 extending outimproved device. Movable plate 13 and the escapements as 2 are restrained to their normal positions. of Fig. 1 by means of tension spring 20, the posts 10 acting as stops against the ends of the concentric slots 18.

Casing 12 has a coverlike member 21 thereon, and formed integrally therewith is a tube portion 22 for guiding a stack of nested cups, said tube portion 22 extending downwardly through movable plate 13 and fitting closely into fixed plate 11. Holes as 23 are provided in the wall of said tube portion 22, through which. escapements as 2 may operate. A glass container tube 24 is provided to contain the stack of nested cups, said tube 24 fitting over the upper end of tube portion 22 and resting against the top of cover member 21. Cover member 21 is contiguous to the upper ends of posts 10, thus keeping escapements 2 located thereon respectively,

My improved device is .so constructed that,

when the parts are in their normal positions previous to operation, the lowermost cup of the stack will be inclosed by the down reaehin tubular end of casing 12. Inside of said to ular end and closely adjacent to the bot tom thereof are provided spring members or fingers as 25, preferably tour in number, for

, arresting the lowermost cup when dis its respective cam portion lfi of late 13, and

blades 3 and 4 have become s ightl sepav ments 2 still continuing their, anti-clockwise 'movement, said foot 9 of blade 4; continues charged, the diametral space within the curved tips of said springs being less than the diameter of the flange of the cup. Thus, before operation, the lowermost cup is shielded from exposure-and, on being discharged, is prevented from falling away from the device, the cup being retained bysaid spring fingers with its lower end projecting beyond the casing in position. for ready removal by the hand of the operator.

The operation of he illustrated form of my improved device is as follows: A stack or nested cups being supported by the flange of the lowermost cup thereof resting upon blades 5 of escapements 2, in the positions shown in Figs, 1 and 2, handle 19 is pulled in clockwise direction, causing radial slots 15 of plate 13 to operate upon downwardly reaching pins 1d of escapements 2 and rotating' said escapenientsqin anti-clockwise 'direction. Blades 3 and 4, in their contiguous relations respectively, are thus caused to enter between the flange oi" the lowermostcupof the stack and the flange of the cup next above the lowermost cup, the stack still being'supported by blades 5'. Y Esoapements 2 continuing in their anti-clockwise direction, blades 5 pass out from under the flange of the' lowermost cop, the stack then being supported by blades 3 projecting under the flange of the cup next abov'e'the lowermost cup. At this time foot '9- of blade of each escapement has come into engagement with rated,all as shown iii-Figs. 3 and l, scapeto mount the incline of cam portion 16, until handle 19 has come to the end of its arness stroke by bringing the ends of slots 18 against posts 10, at which time blades 3 and lof the respective escapements have reached their widest point of separation and the lowermost cup has thus been completely separated from the stack, all as shown in Figs. 5, 6 and 7, Handle 19 then being released, plate 13 and escapements 2 are returned by spring 20 to their normal posi- I and described is illustrative of my invention and changes may be made within the scope of the claims without departing from the spirit of my invention.
